KNITTING- MACHINE.

Original application filed September 19, 1922, Serial No. 589,094.Divided and this July 18, 1924. Serial No. 726,793.

The present specification is a division of that of application forLetters Patent of the United States filed Sept. 19, 1922, Serial No.589,094: now Patent No. 1,525,610, Feb. 10, 1925.

In the accompanying drawings Figure 1 is a side elevation ofthe patternmechanism in connection with the knitting machine.

Fig. 2 is a lan view.

Fig. 3 is a p an view of part of the pattern mechanism.

Figs. 4: to are views of details.

Fig. 11 is a side view of one of the pull 7 bars, the slide to which itis connected and the connection between the slide and the rock shaft.

Connections I leading from the pattern drum to the parts of the knittingmachine to be controlled involve pull bars 27 and 27* in groups of fourpivotally connected re-- spectively to slides and 25 and other pull bars67, 76, 80, 80, also pivotally connected to appropriate slide bars, inturn connected with the parts of the'knitting machine which are to becontrolled.

Each of the pull barsrests upon pins 28 mounted in a carrier bar 29, soas to slide freely therein, in a substantially vertical direction. Thiscarrier bar has movement up and. down in relation to the perforatedpattern strip or jacquard device which in the present case consists ofanendless sheet of flexible material, as paper 30, passing over a patterndrum 30 referred to more fully hereinafter. The up and down movement ofthe pin carrying bar is derived from a cam 31 arranged coaxially withthe needle cylinder and adapted to operate against a roller 32 carriedby a slide 33 which is guided in the bracket 34. This slide bearsagainst an eccentric pin 35 carried by a rocking arm 35 which ispivotally mounted at 36 and is connected with an arm 37 which hasthereon the pin carrying bar 29. A spring 38 presses the arm down andthe cam 31 through the connections described raises the pin carryingbar. .When the pin carrying bar is raised it engagesthe heads of thepins and holds them up. The jacquard strip is perforated and is movedstep by step by the intermittent movement of the drum 30 which has teeth3O, engaging marginal openings in the strip, Now when as will bedescribed hereinafter.

application filed the pin carrying bar moves down, any pin which findsan'opening in the paper strip will pass therethrough, but any'pin whichstrikes an imperforate part of the strip will be held up despite thefact, as just stated, that the pin carrying bar has lowered. The pinwhich passes through the perforation in the paper strip willof coursemove down and thiswill allow the pull bar say 27,

Fig. 1, the pull bar 27which has fallen will i be pushed leftward anddrawing upon the slide 25 will operate the arm 23, which engages itsnotch 25, and turn the shaft 23, thus swinging the arm 22 towards theright and moving the plunger carrier 15 rightward to bring the plunger14 under the proper push bar. 13 for operating the corresponding yarnfeed finger into operative position, when the lifter plate 16 movesupwardly. The train of connections just described will be returned tonormal position, as will be hereinafter described. The pull bar whichhas been operated, as just described, will be elevated to normalposition by the rise of the pin carrying bar 29 which will elevate thepin upon which said pull bar rests, and when raised to this normalposition the said pull bar will be out of range of movement of theoscillating bar 39, ready for. another action such as just described,when the pattern strip calls for it. As before stated, bars 27 connectedwith j the shoulders 27 of these pull bars are in line with each other,see Fig. 2, but it will be noticed'that the oscillating bar- 39 has aseries of shoulders 39 in stepped relation, and consequently atdifferent distances from the shoulders 27 of the pull bars 27, so thatthe slide 25 will be moved diflerentdistances, according to which one ofthe four pull bars is lowered into range of the osoillating bar 39. Thebar 39 oscillates always through the same length of are, it beingmounted on a frame39 pivoted at 39 to the bracket 34, Fig. 1, and it isoperated If the first one of the pull bars 27 (counting from thebottom'of-Figy2) is the one lowered, then the oscillating bar 39 willmove this the maximum distance, because its shoulders 27 stands nearestto the edge of the bar 39. This pull bar will 1 therefore cause. a fullrightward movement of the plunger carrier 15 and the plunger 14 willselect the right hand push bar 13 to throw the right hand yarn fingerdown to operative position. If the second .pull bar :27. is lowered,there will be some lost motion of the oscillating bar 34 take place, sothat the plunger carrier 15 will not be moved so far to the right as inthe first instance, and consequently the plunger 14 will select andoperate the second yarn finger (counting from the right of thegroup A,Fig. 2) and so on as to the other .pull bars 27, each in order fixedthereon froma slide 25 which is like being operated to a lesser degreethan the preceding one, owing to the stepped formation 39 in relation tothe shoulders '27 of the pull bars.

The train of mechanism just described has relation to the group of yarnfingers A. A similaroperation takes placein relation to the group ofyarn fingers indicated at B, Fig. 2. There is a plunger carrier 15 forthis side of the machine with rod 21, lever 22%, and a shaft .23 whichlatter is arranged axially in line with the shaft section 23 abovementioned, and this shaftsection 23 is operated through an .arm .25

the slide 25 and has four pull bars 27 pivoted thereto, to be controlledby certain of the pins 28 and operated severally by the same oscillatingbar 3.9 when the pins find openings in the jacquard strip through whichto pass when the carrier bar 29 is lowered; 7 i i It will be noted thatthe fingers of group A may be selected in any prescribed order desired,the variations in the. order of selection depending upon thedisposition. of the holes in the jacquard strip, and this is true alsoof the group of fingerssB and the order of selection of one group may beentirely differentfrom that of the other group. In order words, the twogroups are entirely independent of each other'in the sense that theorder of. selection ofthe fingers of one group may vary indefinitely in.respect to the I other group, though the selection in respect to the twogroups is 'derivedfrom-the same source, i. e., the'jacquarol strip.

The push plate 39 is operated by a spring 40 in one direction, thisspring being connected to the swinging frame 39", and in the otherdirection .the operation is due to a cam 141. operating against a roll.42 mountedon sli le' whichabe rs g n an adjusting screw-.43 carried bythe frame. The-eccentric pin 35 of'the lever 35 may be ur ed forjustment of its contacting tion with: the slide .313 by a screw driver,the head. ,Qf tl is..-p i i heingk rzted, and.

adjusted it is held by a set screw 35". The rocking of the frame 39 isutilized for operating the pattern drum step by step, for which purposethe frame carries a pawl 44-to engage the teeth 45 of the drum.

This pattern drum is substantially like that pins 28 pass when anopening in the jacquard strip aligns therewith and when the pin islowered by the bar 29. v In order to return the carrier slide 15 tonormal position at the left'of Fig. 2 after being operated to the'right(it being observed that the pull bars 27 have only the advancingshoulder 27 but not a return shoulder, see Fig. 2) the lever 22 has adownward extension 22 connected by a rod 46 with an arm 47 on a verticalshaft 48 mounted in the fixed base of the machine, and this shaftcarries an arm 50'fiXed thereto whichis in the path of a roller 51 onthe shaft 52 forming a part of the rotary take-up mechanism. Thismechanism'inay be of any suitable type and-needs no detail descriptionherein.

The roll 51 travelling about the axis of the machine will hit the arm 50and through the rock shaft 48 andthe connections just described thelever 22 will be returned to the normal position shown in Fig. 1,withthe selector plunger 14 at the left of the series of push rods 13 andwith the pull bars 27 restored'to'norma-l position. v

The pull bar 67 when lowered and operated by the push plate 39 drawsupon a slide 65 and through lever'63' operates a pawl 62 to turn thering 61 byengaging with its teeth. This ringhas cam surfaces 61, 61 forcontrolling the position of the stitch cam.

The pull bars 76 operated by the push plate 39 are pivotally" connectedwith slides 76 and'when "these are operated certain connections leadingto the needle raising cams are operated for adjusting said cams.

The pull'bars 80, S0 of the pattern mechanism when operated by the pushplate 39 operate slides 79, 79", which through certain connectionscontrol supplemental yarn feed. fingers.

The poll bars 76 have two shoulders as shown in Fig. 9 so that thepushplate 39 will-move these pul'lbars in both directions,

and this is 'true of the other pull bars 36X zontal plane, horizontallymovable slides to which said pull bars are pivotally connected to movein vertical planes, connections operated by the horizontal movement ofthe slides, pins upon which the pull bars rest, means -for raising andlowering the pins to raise and lower the pivoted pull bars, said meanshaving a slip joint engagement with the pins a perforated pattern bandfor demove in vertical planes, connections operated by the horizontalmovement of the slides, pins upon which the pull bars rest,-means forraising and lowering the pins to raise and lower the pivoted pull bars,said means having a slip joint engagement with the pins, a perforatedpattern band for determining the up or down position of the pins, meansfor operating the pattern band, a reoiprocating push bar movablesubstantially horizontally for operating the pull bars when the same aremoved vertically into line therewith, and means for operating the pushbar, certain of the pull bars being connected with the same slide, andsaid push bar and said certain pull bars having shoulders which aredifferentially spaced apart, substantially as described.

In testimony whereof I aflix my signature.
